Hi. I am designing a bedroom for two boys and am REALLY stuck. The room is 104 inches (about 8.7 feet) by 112 inches (9.3 feet) with a ceiling height of 181 inches (about 15 feet!) There is a window running along the 112 inch wall that ends at 95 inches (i.e. it's only 8 feet high, leaving over 7 feet of wall space extending above it). The walls are white, the floor is stone, and I am not going to change anything about the room (not going to knock out walls or make new windows). There is a small staircase leading up to an open loft that overlooks the room and that is not included in the dimensions.

I plan to get a custom bed/cabinetry unit for the 104 inch wall with a bunkbed built in. I like the look of white cabinetry with contrasting wood as in the image below.

My questions are:

1. Do I take the bed unit/cabinetry all the way to the ceiling? If so, do I make the cabinetry above the top bunk all white so that it blends into the wall or do I try to add some wood trim to bring the eye upwards? Please note that any cabinetry units above the top bunk could be accessible from the loft, so it would not be wasted storage space.

2. Do I take the window curtains all the way to the ceiling, and if so, what do I do with all that wasted space above the window?!? Do I put a roller shade behind the curtains and bring it down to the top of the window to camouflage the dead space and make it look like there's an actual window there (I worry this is not going to be very successful since there won't be any light coming through the roller)?

3. If I don't take the drapes to the ceiling, do I try to match the height of the top of the drapes to the height of the top of the top bunk? And what do I do about that space above the ceiling? Just leave it? Decorate it?

3. How far down do I bring the light fixture? Do I leave it high or bring it down to where it would be if the room had an 8 or 9 foot ceiling?

I've tried to do a to-scale drawing to envision this myself. I'm also posting that below.

Any help would be appreciated! Thanks.
